Abstract: 1276615 Sinter bonding metal components NATIONAL-STANDARD C O  2 April 1970 [18 April 1969] 156793/70 Heading C7D A method of sinter bonding metal components e.g. for cladding, or sealing a mine in the bore of a tube, comprises placing a metal part in juxtaposition to a compacted reducible metal compound powder, heating the assembly to reduce the compound and then heating to sinter bond the components together. The metal compound is preferably a steel or iron mine which is inserted into the bore of an extruded metal compound tube formed from a powder mixture of a binder such as corn starch and either iron oxide formed from spent pickle liquor, or copper oxide, or a mixture of iron oxide nickel oxide and Fe Cr which produces a stainless steel on reduction. The metal compound particles are preferably < 10 microns with an average size of 0À8 microns and with 90% weight < 2.5 microns. With the iron - iron oxide assembly, heating is at 1100 ‹F. and 2100 ‹F. , with the iron - copper oxide at 700‹F. and 1800‹F. and with the iron - stainless steel components at 1100‹F. and 2200‹F. Formulae are included for calculating the shrinkage of the green metal compound in order to determine the required mine size for a given tube bore diameter. The mine diameter is preferably less than the inner diameter of the green tube and the same diameter as the sintered inner diameter at the bonding sections.

Title: Improvements in or relating to tape readers and the like
Inventor: GAITE HAROLD DODIMEAD
IPC: H04L17/12
Filed: 1958-05-20
Abstract: 881,427. Type-printing telegraphy. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. May 13, 1959 [May 20, 1958], No. 16186/58. Class 40(3). A tape reader comprises a number of rows of peckers arranged to mate with successive rows of holes in the tape so that several characters may be read simultaneously or in non-consecutive order. One row of eight peckers 11 is shown. Each pecker is connected to a spring 12 separated from a spring 15 by an insulator 16. If a pecker enters a hole in the tape, spring 12 makes contact with bar 14 while if there is no hole the pecker is in a lowered position and spring 15 contacts bar 17. The tape transport mechanism comprises means for gripping the tape and for pulling it forward or pins which engage feed holes in known manner. In the latter case the mechanism comprises relays 2, 3, which rock member 5 about point 6. Tape platform 7, which is carried by member 5, moves substantially vertically to lift the tape clear of the peckers 11. As the peckers are cleared the transport perforations engage with pins mounted on an extension 21 of member 18 which is rocked, by means not shown in Fig. 1, in a plane perpendicular to the plane of the paper to move the tape. The apparatus ceases to operate if no tape is present, or if the tape becomes too tight, the former being sensed by an additional pecker associated with lever 31 and micro-switch 37, and the latter by a further lever, over which the tape is passed, and which operates a second micro-switch.

Abstract: 1,150,432. Chemical contact apparatus. Continuous discharge mixing apparatus. FARBENFABRIKEN BAYER A.G. 13 April, 1966 [15 April, 1965], No. 16254/66. Headings B1C and B1F [Also in Division C1] In a reactor having a frusto-conical combustion chamber at one end, a first stream enters axially at a velocity up to 20m/sec., while a second stream is blown in transversely at the side of the cone with a velocity of 30-120 m/sec. through nozzles the axes of which have a transverse component and are inclined to a transverse plane at an angle of 0-25. The product of the specific gravity and velocity for the transverse stream is 10-100 times that for the axial stream, and the diameters of the lateral inlet nozzles 1/5- 1/20 of the distance from the nozzle outlets to the combustion chamber axis. In Fig. 1, the first stream enters at 1 and the second from conduit 6 and ring 7 by nozzles 8. A third stream of "inert" gas enters via nozzles 11, from conduit 9 and ring 10, below ring 7, and is used to prevent deposition of reaction products on the walls of the reactor. Instead of the arrangement shown, the reactor walls may be of a porous material, through which the third stream passes. The third stream may also carry an inert granular material to remove any reaction products from the walls by friction. The process may be applied to the oxidation of vaporizable metal halides to oxides such as TiO 2  for use as pigments, using O 2 , or air at temperatures of 800-2000C. The reactants are preheated by conventional methods, and the oxygen/Ti Cl 4 , ratio may be 1-1.3. Oxygen may be preheated by mixing with CO before entry into the reaction chamber. Modifying agents such as Al 2 O 3 , ZrO 2 , SiO 2 , steam, and compounds of alkali metals and alkaline earth metals may be included in the reaction mixture as a powder or aerosol. The reaction mixture may be seeded by a variety of methods such as 0.5-5% of TiO 2  made by reaction of a partial stream of TiCl 4  with steam, oxides of N, O 2 , 0.5-5% of SiO 2  made from SiCl 4  with steam, O 2 , or oxides of N, the product of reacting a mixture of TiCl 4  and SiCl 4  with compounds of alkali or alkaline earth metals, or 0.5-5% of the product obtained by reducing TiCl 4  with H 2 .

Title: Improvements in or relating to collimators for radiotherapy equipment
IPC: G21K1/04
Filed: 1965-04-20
Abstract: 1,083,402. Collimator. A. SHEWCHENKO. April 20, 1965 [Jan. 6, 1965], No. 16576/65. Heading H5R. An adjustable collimator to define the area of the beam incident on a patient in radiotherapy, comprises four longitudinal members 1-4, spaced equally around a central longitudinal axis, each member 1-4, having spaced along it a number of transverse limbs (e.g. 12, 14, 16, 18), the gaps between limbs on one member 1-4, being occupied by the limbs on an adjacent member. At the end of the collimator adjacent a radio-active source (105, Fig. 5, not shown), the members 1-4 have hinge brackets, e.g. (21, Figs. 3, 4, not shown), by which they are hinged to an annular member (102) to which is attached the collimator frame or casing (100). The collimator may rotate as a about its own axis by virtue of a flange (110) at the end of the frame (100) away from the source, being mounted on ball-bearings in a unit ring (112) attached to the radiotherapy unit. An outer casing (106) and back plate (103) similarly form part of this unit. Adjustment of the collimator members 1-4 to cause them to pivot out or inwardly, with respect to the central axis, on the hinges, is through two drive shafts (150, 160) the former controlling the side members, the latter the top and bottom members. The front ends of members 1-4 carry guide brackets (19, 29 &c.) on which are mounted rollers (170) on shafts (171). Associated with the collimator frame (100) is a housing in which the drive shafts (150, 160) are accommodated and also annular cam members (130, 135) which are rotatable by the shafts (150, 160) respectively. The cam members each carry two opposed cam track arms (134, 136) in which the rollers (170) are forced to move when the cam members rotate, thus carrying the limbs 1-4 into the positions required. The material used for the collimator, in order to absorb γ-radiation, may be uranium, tungsten, lead, iron &c. A feature of the shape of the transverse limbs of the collimator is that they are formed as segments of individual annuli, based on the same centre of curvature.
